PIPE-HANGER INSERT.

Specification of Letters Patent.

Application filed August 16. 1917. Serial No. 186,446.,

ed to be embedded in concrete construction work such as a ceiling, and has for its objects, among others, to provide one which is cheap and inexpensive to manufacture, durable and substantial in design, and one which can be readily and accurately arranged and rigidly set in longitudinal alinement with a plurality of other inserts so that when drops or pipe hangers are attached to them, they will present a straight line which has heretofore been very diflicult without bending the hangers.

A further object of the invention is to produce an insert of the above-stated character which is so constructed that the same may be eflectively and conveniently reinforced within the concrete structure in which the same is embedded against all liability of it being casually loosened or displaced.

With these and other objects in view, the invention consists in the improved construction, arrangement and combination of parts hereinafter fully described and afterward specifically claimed.

Referring to the drawings,

Figure 1 represents a perspective view of our improved construction of insert arranged in operative position within the ceiling and a pipe hanger supported therefrom.

Fig. 2 represents a vertical sectional view through the insert, and

' Fig. 3 represents a bottom plan view of the insert.

Similar characters of reference are used to denote corresponding parts throughout the accompanying drawings and the following description.

In order that the construction and operation of the invention may be readily comprehended, we have illustrated an approved embodiment thereof in the accompanying drawings and will now proceed toifully describe the same in connection with said drawings, in which the reference numerals 1 and 2 indicate the end and side walls of the insert casing, and 3 .and 4 the bottom and top walls respectively. The bottom wall 3 is provided with a T-shaped slotvwhich embodies a longitudinally disposed restricted passage 5 which communicates at one end withan enlarged-opening-S.

Each of the end walls 1 'is "formedat a point intermediate its side edges with a ver-- tically disposed-rib? whichv is PIOVIdGdnO II. 'itsbottom portion with a depending spur 8 for a purpose which will presently appear.

The top wall 4 is'provided circumferentially with an upwardly and outwardly curved laterally projecting flange 9 which is disposed in a plane slightly above the top wall. Between the top of the end wall of the casing and the upwardly and outwardly curved portions of the flange elongated slots 10 are provided through which a reinforcing wire or rod 11 may be passed in order to rigidly support the insertwlthin the concrete ceiling or other structure in which the insert may be arranged in a rigid and effective manner against casual displacement. It will be seen by reference to Fig. 2, that when the reinforcing rod is disposed through the slots 10, that the laterally projecting flanges 9 will rest upon it, and thushelp in connection with the cement or concrete, to rigidly support the insert.

The flanges 9 extending along the longitudinal sides of the top wall are each provided with notches 12 for the reception of nails or other securing elements in temporarily holdin the insert in position while the ceiling is eing molded or poured.

The numeral 13 represents the stem of a pipe hanger and is pivotally connected as at 14 to a strap hanger 15 adapted to support a pipe .16. The upper end of the stem is threaded for the reception of a nut 17 WhlCh is preferably square.

In the use of the insert, and we Wlll say for instance that it is desired to use a plurality of them, they are arranged upon the ceilin form or templet boards in longitudinal a moment with each other. After the inserts have been so arranged, pressure is brought to bear upon the topsof them sufficiently to press the spurs S'into the form Patented Nov. 19, 1918.

in testimony whereof We have signed our names to this specification in the presence of two subscribing Witnesses.
